The cam looks fine to me, if you don't think it is good have a shop polish it, it will look brand new again. Roller cams last one heck of a long time. The same design goes into the Duramax Diesel, no one tears them down for a cam and they last 300,000+ miles. Not saying it is pretty but I don't see anything on that cam that will make a lifter wheel fail. Roller cams are durable. When I see bad ones it is because the owner had a bad lifter and kept driving it while it was broken till the bad lifter did damage to the cam surface.
Every lobe needs close inspection to make sure you don't have hidden damage. It sounds like you already made a decision to install a new cam. At least the Non AFM lifters cost much less!
